Specification of Letters Patent.

' Application filed June 16, 1910 Serial No. 567,225.

To all whom it may concern: Be it known that I,- MAX Guam,

' in the city and county of Philadelphia, State of Pennsylvania, have invented acertain new and useful improvement-in a certain automatic .ma gazine needle-holder ,to be used in disk talking-machines in applying a new method of using needle after needle without removing the same immediately after playing a record.

The invention applies to all disk talking machines and consists of a multiple-revolving needle holder mounted on a supporting arm by which attachment is made to thereproducer of the talking machine. a

The whole contrivance operates in such a way as to allow all the needles to be used consecutively and afterward removed all at one time, and others put in their place.

This device may be made of gun metal, aluminum, brass, iron, steel, nickel or other material or materials.

Figure 1 represents a rear el wation. Fig; 2 a front elevation with ou er plate and thumbscrew. removed. Fig. 3 represents a central section and Fig. at, is anassembly of all the parts showing the connection with the reproducer M- of the machine, as the device would appear in actual use with needles in place resting upon the record P which is supported'on the turntable B.

This device consists of a supporting arm D Figs. 1-2 and 3 on which is mounted two circular plates and J Fig. 3, separated :tromthe supporting arm D by a washer K Fig. 3 to prevent the rubbing of thelower plate A and the supporting'arm D. These two plates A. and J revolve'upon a pin 0 Figs. 1--2 and3through their center and are clamped together by means of a thumbscrew H Fig. 3 which works in and out on a thread cut in the outer end of the pin or axle C. This pin or axlepasses through the supporting arm D Figs. 1 and 3 and mounts on its inner end a toothed wheel G Figs 1 and 3 which operates againsta dog F Figs. 1 and 3 so as to form a ratchet. The central pin or axle C is made to revolve freely through the supporting. arm D and outer or cover plate J as shown in but is fastin the lower disk or plate A and the ratchet wheelG. The innercircular'plate or disk A Figs. 1-2 and 3,-isslotted .or

' grooved as shown at B Figs. 2 and 3 on lines radiating from its center to such a residing,

cider and of the same diameter as the inner magazine plate A Fig. 3 and is held against it by means of a thumbscrew H, Fig. 3 operating on a screw thread cut in the central pin C asshown in Fig. 3.

On the outer surface of the cover-plate J a star or othei markis made t9 provide a starting point so that none of the needles may be used asecond time. thumbscrew H Fig; 3 is turned so as to jam the two plates A. and'J together and thus firmly secures the needles in the pockets 01' grooves of the plate A additional rotary pressure on the thumbscrew in a clockwise direction will cause each needle to consecutively assume a vertical position and ready forplaying, being so controlled by the ratchet arrangement G and F Fig. 8. A reverse motion of the thumbscrew releases the cover plate J, thus enabling the needles to be removed and the magazine refilled again.

the supporting arm inserted in the needle or screw clamp ofthe reproducer-can be round, square or any other shape.

Slight modificationsmight be made in the construction here shown without departing from the spirit of my invention. and I therefore do not wish to be limited to its exact construction.

What I claimis:-

1.' A device of the class recited comprising a fixed support, a rotatable disk-like member equipped with a plurality of radially disposed detachable needles, means for clamping said needles with respect to the said member and means forpreventing ret: rograde movement of, said member.

2. A device of the class recited comprising a fixed support. a disk-like member provided with a plurality of radially extending grooves rotatably mounted with respect to said support, needles for said grooves, means for clamping. said needles within said grooves and means for preventing retroademovement of said member.

3. A'device of the class recited comprising a fixed support, a disk-like member provided with a plurality of radially disposed grooves rotata-bly mounted with respect to said support, a needle within each groove, a removable plate for preventing the escape of the needles, meansfor clamping the vplate to place and means for preventing escape 0 ing provided with a plurality of radially disposed needle receiving grooves, needles for said Erooves, aplate for preventing the clamping: the plate to the said member whereby said member may be rotated-clocktively connected between said support and member for preventing retrograde movement of said member.

In Witness whereof I have-hereunto fixed my signature in the presence of two subscribing witnesses.
